Application filed December 6, 1927. Serial No. 238,144.

This invention relates to improvements in lubricator mechanism for the picker spindles for so-called spindle, pick looms and it is the general object of thelinvention to provide a device of this kind having a flexible element to engage the picker spindle to leave a small deposit of oil or other lubricant I thereon. 1- Spindle pick looms usually employ a rod 1 parallel to the path of the lay located behind the shuttle to guide the picker which is made of raw hide and has a bearing portion to slide along this rod and also has a shuttle tip engagingportion. The picker stick engages the picker between the picker bearing portion and the shuttle engaging portion to move said picker inwardly when the lay is moving rearwardly and is substantially midway between its extreme forward and rearward positions. It is found that the picker spindle is not always properly lubricated and it is a common experience to find these rods hot from the friction of unoiled pickers. It is' an important object of my present invention to provide a lubrieating device mounted independently of the lay and having a flexible element to engage the picker spindle preferably at a time when the lay is in its rearmost position, ible element yielding when in contact with the spindle so that fine adjustments are not necessary. J I

It frequently happens that the weaver will desire to pick the shuttle by hand and this operation is usually carried out with the lay substantially in its rearmost position. This operation is permissible'because'of the flexible character of the'lubricating element The invention is particularly useful in looms wherein the picker sticks work in alternation. In such a loom the picker is active: on one pick and idle on the rest, and it is a further object ofthe invention to move the lubricator for each spindle into oiling position when the corresponding picker is idle.

. I With these and other objects in view which will appear as the description proceeds, my

invention resides in the combination and arrangement of parts hereinafter descrlbed and set forth 1n the claims.

In the accompanying drawlngs, wherein I have shown a convenient embodiment of my invention,

Fig. 1 is an end elevation of a loom having my mproved device mounted thereon,

F 1g. 2 is a front elevation of the lubrieating device showing the same applied to both ends of the loom, the intermediate portlon of the loom being omitted.

Fig. 3 is an enlarged top plan view taken in the direction of arrow 3, Fig. 1,

Fig. 4 is an enlarged vertical section on l1ne 4.l of Fig. 2, 1

F 1g. 5 is a front elevation of the flexible spindle engaging element taken in the direct on of arrow 5, Fig. 4, and Fig. 6 is an enlarged detail vertical sectlon of the upper end of one of the flexible lubricator element carriers.

Referring to the drawings I have shown a loom frame 10 having a lay 11 which swings about a rocker shaft 12. I The lay moves back and forth toward and from the said spindles a picker 15 indicatedin Fig.

4 in dot and dash lines.

I The bottom shaft 15 is caused to rotate in well-known manner and as shown herein receives a complete revolution every alternateybeat-up of the lay. The device is shown in connection with a lay having a single box at one end so that the picker sticks will be alternately operative. The

matter thus far described is of the usual construction and forms no part of my present invention.

.In. carrying my improvements into effect I provide each end ofthe loom with a lubricating mechanism and as these are both the same except for the setting of the driving mechanism withrespect to the bottom shaft 15 I will describe but one of them; A

bracket 20 is secured to the loomsideand is provided with a stud 21 on which rocks a lever- 22. The lower end of said lever is connected by a link23 tov a stud 24- adjustably mountedin a slot 25 in crank arm'26. Said crank arm .is secured to the bottom shaft 15 by set screw 27 so that its angular position with respect to the bottom shaft may be varied in order that'the osclllation loo of the lever 22 maybe altered relatively to the cycle of the pick. The stud 24; is held in position by a nut 28 which together with the slot permits a variation in the throw or extent of oscillation of said lever 22.

The upper end otthe lever is provided witlran oil container 29 having a depending foot 30 secured by bolt 31 to the upper end of the rocking lever 22. The container is formed as shown in Fig. -l with a cup or oil reservoir 32 closed on four sides and the bottom but open on the top to receive a carrier 33. Said carrier as shown in Fig. 4 is substantially ld shaped in form and the left hand vertical portion thereof has struck therefrom a slight boss 34 which hts under a head 35 formed on the left wall .01 the reservoir 32 as viewed in Fig. 4-. The carrier is preferably made oi resilient material so that the left por'ion 83 may be sprung away from the adjacent wall or the oil reservoir as indicated in dotted lines in Fig. i i

That part oil the device which had direct contact with the picker spindle 14 comprises a large number of bristles 36 which are held to the carrier 33 by means of a pair ofclips 37 which as indicated in Fig. -l may be riveted to the right hand vertical portion 33" ofthe carrier. The bristles may be similar to those commonly employed in making "brushes and extend to the bottom of the oil so as to be permanently in contact with the lubricant mdicated at L in Fig. l.

In the operation of the loom the bottom gage the spindle at any point thereof which ;1s passed by the plcker and it Wlll be evident because of the flexible nature of the element 36 that it is not necessary to have the throw of the'lever very accurately timed inasmuch as .said bristles will flex or end to the left as viewed in t if the lever is given a slightly greater motion than is necessary to bring said bristles in contact with the spindle. its the picker moves along the spindle the small amount 0! oil deposited on the latter by the bristles is picked up and moved along said spindle with the pie-her so that the spindle is heft supplied with oil.

As previously statedit sometimes happens that the weaver desires to picl: the shuttle byd and and this will ordinarily happen when the lay is in its rear-most position in order that the shed may be wide open. In th s position, however, the bristles may be in contact with the spindle but because of the flexibility of the bristles they will bend to loom.

UL) ot the carrier aihuding means by which the operator can grasp and remove the carrier.

During the running of the loom the picker sticks will be alternately operative and the oiling device will be so timed by the setting oil the cranks 26 that each lubricating device will be located behind the range of movement of its corresponding picker spindle when the picker for the latteris to be active, that is, the bristles oi each eevice are in lubricating position with respect to the spindle only on alternate beats oi the loom. 1 n 1 nv1bv],"7 "T1131; -n]

1 us .lCbllle is ac rim en raring ilc clan s 26 at the two ends of bottom shaft 15 set in opposite directions. Thepurpose of this is to permit the picker to move alone he L in die without interlierence and to pern'rt the lubricating device to engage the :-:pindle at such times as the picker will not engage the bristles.

From the foregoing it will be seen that ill) I have provided a. very simple means for lubricating the picker spindles for looms and that said device includes a set of 'brFstles which by their flexibility not only render unnecessary delicate settings of the operating meehanisnrbut also permit the manual operation of the picker and shuttle by the weaver when the lay is in its rearmost position.-

Having thus described my invent on it will be apparent that changes and n'iodifications may be made therein by those skilled in the art withoutdeparting from thespirit and scope of the inventon and I do not wi 1 to helimited to the details herein dfsclosed, but whatl claim 1.
